A Charge Is Accelerated from Rest Through a Potential Difference

Question 28

Multiple Choice

A charge is accelerated from rest through a potential difference V and then enters a uniform magnetic field oriented perpendicular to its path.The field deflects the particle into a circular arc of radius R.If the accelerating potential is tripled to 3V,what will be the radius of the circular arc?


A) 9R
B) 3R
